How should the LTM Specialist resolve this issue?
What is a benefit provided by F5 Enterprise Manager?
Users are unable to reach an application. The BIG-IP Administrator checks the Configuration Utility and observes that the Virtual Server has a red diamond in front of the status. What is causing this issue?
An LTM Specialist is troubleshooting a problem on an eCommerce website. The user browses the online store using port 80, adding items to the shopping cart. The user then clicks the "Checkout" button on the site, which redirects the user to port 443 for the checkout process. Suddenly, the user's shopping cart is shown as empty. The shopping cart data is stored in memory on the server, and the default source address persistence profile is used on both virtual servers.
How should the LTM Specialist resolve this issue?
Refer to the exhibit.
A BIG-IP Administrator creates a new Virtual Server. The end user is unable to access the page. During
troubleshooting, the administrator learns that the connection between the BIG-IP system and server is
NOT set up correctly.
What should the administrator do to solve this issue?
A BIG-IP Administrator uses a device group to share the workload and needs to perform service on a BIG-IP device currently active for a traffic group. The administrator needs to enable the traffic group to run on another BIG-IP device in the device group. What should the administrator do to meet the requirement?
In preparation for a maintenance task, an LTM Specialist performs a "Force to Standby" on LTM device Unit 1. LTM device Unit 2 becomes active as expected. The maintenance task requires the reboot of Unit 1. Shortly after the reboot is complete, the LTM Specialist discovers that Unit 1 has become active and Unit 2 has returned to standby.
What would cause this behavior?
An LTM Specialist plans to enable connection mirroring for a virtualserver in an HA environment.
What must the LTM Specialist consider before implementing the configuration change?
An LTM device supports two power supplies. The value of the BigDB key "platform.powersupplymonitor" is equal to enable.
Where would the error message be visible if one of the power supplies fails or is NOT plugged in?

An LTM Specialist configures a virtual server that balances HTTP connections to a pool of three application servers. Approximately one out of every three connections to the virtual server fails.
Which two actions will resolve the problem? (Choose two.)

Refer to the exhibit.
A failover has just occured on BIG-IP1. BIG-IP2 is now active and manages traffic as expected. Both Bigip's are set with a gateway failsafe to check the reachability of the main border router. Switches have performed as expected.
Where should the LTM Specialist check for potential issues?
A BIG-IP Administrator must configure the BIG-IP device to send system log messages to a remote syslog server In addition, the log messages need to be sent over TCP for guaranteed delivery. What should the BIG-IP Administrator configure?
A virtual server for a set of web services is constructed on an LTM device. The LTM Specialist has created an iRule and applied this iRule to the virtual server:
when HTTP_REQUEST {
switch [HTTP::uri] {
"/ws1/ws.jsp" {
log local0. "[HTTP::uri]-Redirected to JSP Pool"
pool JSP
}
default { log local0. "[HTTP::uri]-Redirected to Non-JSP Pool"
pool NonJSP
}
}
}
However, the iRule is NOT behaving as expected. Below is a snapshot of the log:
/WS1/ws.jsp-Redirected to JSP Pool
/WS1/ws.jsp-Redirected to JSP Pool
/WS1/ws.jsp-Redirected to JSP Pool
/WS1/WS.jsp-Redirected to Non-JSP Pool
/ws1/WS.jsp-Redirected to Non-JSP Pool
/WS1/ws.jsp-Redirected to JSP Pool
/ws1/ws.jsp-Redirected to Non-JSP Pool
What should the LTM Specialist do to resolve this?
Refer to the exhibit.

An LTM Specialist has recently taken over administration or an LTM devicethat has experienced resource availability issues. The LTM device will need to be solely used for load balancing and SSL offload. Previously, the LTM device was also used to provide statistical analysis of application traffic. However, that functionality has been moved to a third party solution.
Based on the output below, which configuration change should be made to ensure the LTM module receives the most amount of resources?
Remote office users are having performance issues with a virtual hosted on the F5 LTM. The LTM Specialist reviews the configuration for the virtual server and determine that some settings are set with default profiles.
Which profile should the LTM Specialist enable to improve virtual server performance?
A BIG-IP Administrator uses backend servers to host multiple services per server. There are multiple virtual servers and pools defined, referencing the same backend servers.
Which load balancing algorithm is most appropriate to have an equal number of connections on each backend server?
An LTM Specialist is troubleshooting an issue with a new virtual server. When connecting through the virtual server, clients receive the message "The connection was reset" in the browser, although connections directly to the pool member show the application is functioning correctly.
